Abstract

본 발명은 자동차의 선루프에 관한 것으로, 특히 자동차의 선루프 구동시 햇빛의 방향을 감지하여 자동으로 햇빛을 차단시킴으로써, 운전자에게 쾌적한 차내 환경을 제공할 수 있도록, 선루프를 동작시키기 위한 선루프 동작 스위치와, 상기 선루프 동작스위치의 턴-온시 햇빛의 방향을 감지하는 태양각 센서, 상기 태양각 센서로부터 감지된 햇빛의 방향이 운전자를 향하고 있는지 비교 판단하는 비교기, 상기 비교기로부터 출력된 신호와 상기 선루프 동작스위치 신호를 논리곱 연산하는 앤드 게이트, 상기 앤드 게이트의 출력에 의해 온/오프 구동되는 릴레이 및, 상기 릴레이의 턴-온시 인가된 전압에 의해 액정분자의 배열이 변경되어 햇빛을 차단시키는 선루프로 구성한 액정을 이용한 선루프의 햇빛 차단장치에 관한 것이다.The present invention relates to a sunroof of an automobile. In particular, the sunroof for operating a sunroof so as to provide a comfortable in-car environment to a driver by automatically blocking sunlight by detecting a direction of sunlight when driving the sunroof of an automobile. An operation switch, a sun angle sensor detecting a direction of sunlight at turn-on of the sunroof operation switch, a comparator comparing and determining whether the direction of sunlight detected by the sun angle sensor is directed toward a driver, and a signal output from the comparator; An array of liquid crystal molecules is changed by an AND gate that performs an AND operation on the sunroof operation switch signal, a relay driven on / off by an output of the AND gate, and a voltage applied at turn-on of the relay to block sunlight. It relates to a sunroof of the sunroof using a liquid crystal composed of a sunroof to make.
